Basic Info for Ch 42

Ch 42 – Circulation and Gas Exchange
** The questions below refer to mammalian systems (remember, these are basic info questions).  The systems and adaptations of other animal groups are also discussed in this chapter - don't overlook these in your reading and note-taking.

1. What is the overall function of the circulatory system? The respiratory system? Why are they so closely connected?
2. What are the main types of blood vessels, and what are their functions?
3. Be able to label the structures of the heart on a diagram, like figure 42.6.
4. Describe the path of blood flow and what is happening at each location.
Here is a suggestion for help with this question! -
Go to the textbook website: http://wps.aw.com/bc_campbell_biology_8ap/ , and go to chapter 42.  Under section 42.3, click on “Activity: Path of Blood Flow in Mammals.” Watch part 1. Now, watch it again (it goes by fast!). Then, click on “next” (upper right), follow the directions, and test yourself on the path of blood flow. Use your book for help (figures 42.5 and 42.6). Finally, go back and click on “Activity: Mammalian Cardiovascular System Function.” Again, follow the directions and answer the questions. ** Your goal with these activities is to be able to describe the path of blood flow and what is happening at each location. Take notes on whatever is helpful to you. **
5. What is the lymphatic system, and what is its function?
6. What are the components of blood, and what are their functions?
7. How is oxygen transported in the blood?
8. How is carbon dioxide transported in the blood?
9. Name the structures of the respiratory system. Give the structures in the order that oxygen travels through them, from when it enters the body to when it reaches the bloodstream.
